1 Check tapered roller bearing and bearing races.

The tapered roller bearings and bearing races can be used again if:
^ the tapered rollers and bearing races have a smooth, grey running track
^ no discoloration (from severe overheating, etc.) is found.
^ the roller cage and the face ends of the tapered rollers are not damaged.
^ the bearing races sit tight in the wheel hub.
The tapered roller bearings and bearing races cannot be interchanged. If damage is present, a new front wheel hub must be installed.

The replacement front wheel hub is supplied complete with both tapered roller bearings and radial shaft sealing ring.
